Desenvolvimento e validação de método para determinação de agrotóxicos em grãos de soja

TL;DRAbstract

Soy is one of principal Brazilian exportation products of Brazil as it is much used as a foodstuff because of its functional properties: rich in vitamins, proteins and minerais. The increasing quantity and quality of soy demands a constant and even expressiva application of pesticidas during soy cultivation. On the other hand, for preservation of public heath, since most pesticidas may be prejudicial to health, the main regulatory agencies impose the maximum residues limits of pesticides in food. Thus, in this work, a method to determine lhe main pesticides applied in soy cultivation (imazethapyr, imazaquin, metsulfuron-methyl, carboxin, chlorimurom-ethyl and tebuconazole) using matrix solid phase dispersion (MSPD) as the extraction technique, followed by a clean-up step and subsequent chromatographic analysis by high performance liquid chromatography -diode array detection (HPLC-DAD), was developed and validated. The results have shown that MSPD is a suitable extraction procedure for
